[Dave Gilbert <ubuntu@xxxxxxxxxxx>]

I'd like to suggest something;
   It should be possible to build a ppa'd kernel with just that change reverted, then that kernel could be used to see if other apparently similar bugs (like bug 1243904) are actually the same issue without other users having to do the same bisect (especially if they're not technically comfortable doing them).

I'd note that I triaged 1243904 to 'high' on the basis of the
bugs/importance entry of 'A problem with an essential hardware component
(disk controller, built-in networking, video card, keyboard, mouse)'

Title:
  [LG Electronics LW25-B7HV] Keyboard not working

Status in The Linux Kernel:
  Unknown
Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  Keyboard on an LG LW25 laptop is not functional anymore on Ubuntu 13.10. Any 3.8.x Ubuntu kernel works fine. Starting with 3.9.0, the keyboard breaks. External keyboards are still fine. A kernel bisect suggests that the first bad commit is:
  be2d7e4233a4fe439125b825470020cef83407d5
  Input: atkbd - fix multi-byte scancode handling on reconnect

  WORKAROUND: Use kernel parameter i8042.dumbkbd=1
